Hey Rockhoppernc!! CONGRATS!! That is truly a unique find!! Interesting Design!! Took a lot of thought process in making that one!! GOOD LUCK and GOOD HUNTING!! VERDE!!
Just an off the wall guess. But could it posdibly be a lead mold to make fishing weights or something of the sort...seems like it would make to connected lead half spheres that would fold to make a big lead fishing weight...just maybe haha
